The growth of Diaspora - A decentralized online social network in the wild
2012 Proceedings IEEE INFOCOM Workshops, 2012Co-Authors: Ames Bielenberg, Lara Helm, Anthony Gentilucci, Dan Stefanescu, Honggang ZhangAbstract:The Diaspora network [1] is a recently launched decentralized online social network with over 216; 000 users as of November 16; 2011. It is a network of independent, federated Diaspora servers that are administrated by individual users who allow Diaspora users' profiles to be hosted on their servers. In this paper we take a first look at the Diaspora network's overall growth in terms of number of users, the topology of its interconnected servers, and the reliability of those servers. We also present a simple analysis to explain the growth of the Diaspora network. Our timely measurement study of a real-world decentralized online social network sheds light on the evolution of such a network in practice, and provides valuable observations and insights that can help the future design and implementation of decentralized online social networking.

africans in the Diaspora the Diaspora and africa
African Affairs, 2000Co-Authors: Emmanuel AkyeampongAbstract:ONGOING AFRICAN DiasporaS, the recent growth of Atlantic and diasporic studies, the globalization of capital and culture, the technological revolution and the breakdown in information boundaries, all these have necessitated a rethinking of the African Diaspora and its changing meanings. The nature and composition of the African Diaspora have undergone significant changes over time: from the forced migration of African captives of the Old and New Worlds to the voluntary emigration of free, skilled Africans in search of political asylum or economic opportunities; from a Diaspora with little contact with the point of origin (Africa) to one that maintains active contact with the mother continent; all culminating in the birth of a unique African who straddles continents, worlds and cultures. Today, Africans are found in non-traditional points of migration such as Israel, Japan, Taiwan, New Zealand and Australia. In this diasporic flux, many sociological givens have been challenged and/or transformed: the boundedness of culture and religion; the definition of citizenship; and state-civil society relations, among other things. Intriguing continuities also persist in the existence of trading Diasporas within and outside Africa and in the unfortunate survival of forms of unfree labour in Africa and beyond. When the editors of African Affairs invited me to write something thoughtful and provocative on the more contemporary African Diasporas and their impact on Africa, they gave me quite wide terms of reference. I have chosen to examine the changing nature of Diaspora over time with more emphasis on the twentieth century and its ramifications for African religions and cultures, for the redefinition of political communities, and for the economic potential of the free flow of skilled Africans and African financial capital for African development. Joseph Harris has emphasized the ways in which Diasporas 'affect the economies, politics, and social dynamics of both homeland and the host country or area'.l As an historian, I have chosen to dwell on the historical experience of Diaspora rather than on the equally important discourse on Diaspora that is current in literary and cultural studies, a discourse which nonetheless informs some of the issues examined in this essay, as well as its conceptualization.

Cultural geographies of counter- Diasporic migration: Perspectives from the study of second-generation 'returnees' to Greece
Population Space and Place, 2010Co-Authors: Russell King, Anastasis ChristouAbstract:This paper aims to contribute to ongoing theorisation of Diasporas by a specifi c focus on ‘second-generation return’ – the migration of host-country-born second-generation persons to the birth-country of their parents. We nominate the term ‘counter-diasporic migration’ to describe this particular migration chronotope. Although the ideology of ‘return to the homeland’ is inscribed into most defi nitions of Diaspora, relatively few studies have been made of ‘counter-Diaspora’, where the ‘scattering’ is reversed. Adopting a cultural-geographical perspective, the paper explores some of the core elements that are constitutive of second-generation relocation to the ancestral homeland: specifi cally the migrants’ complex and ambiguous views of ‘home’, ‘place’, ‘belonging’ and ‘identity’; or, from the emic perspective of the migrants, the ‘who I am’ in the ‘where I am’. The paper draws on some results from ongoing research by the authors into the second-generation return of Greek-Americans and Greek- Germans to Greece, as well as on other studies of counter-Diaspora around the world.
